Design of decoupling networks for circulant symmetric antenna arrays
Coetzee, Jacob & Yu, Yantao (2009) Design of decoupling networks for circulant symmetric antenna arrays. IEEE Antennas and Wireless Propagation Letters, 8, pp. 291-294.
Small element spacing in compact arrays results in strong mutual coupling between array elements. Performance degradation associated with the strong coupling can be avoided through the introduction of a decoupling network consisting of interconnected reactive elements. We present a systematic design procedure for decoupling networks of symmetrical arrays with more than three elements and characterized by circulant scattering parameter matrices. The elements of the decoupling network are obtained through repeated decoupling of the characteristic eigenmodes of the array, which allows the calculation of element values using closed-form expressions.
